To heat a material such that certain temperature dependant changes occur, examples being oxididation, reduction, phase changes or the loss of chemically-bound water. Ceramic raw materials which are calcined include clay, bone and talc. Candling The lower temperature stage of some firing cycles used to complete the drying of the ware. Carbonizing
Mastic is excreted by the resin glands of certain trees [3] and dries into pieces of brittle, translucent resin. When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to pine and cedar. cleaning mastic tears in Pyrgi

Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
Because the major components of an alkyd coating, i.e. fatty acids and triglyceride oils, are derived from low cost renewable resources, the cost of alkyd coatings has remained very low despite the ever-increasing cost of petroleum, which is the predominant raw-material source of most other coatings such as vinyls, acrylics, epoxies and ...
